WILLIAM M. ivirrcnntn, or nonisvrttn, KENTUCKY.

nA n-An'cnom To aZZ whom it may concern."

Be it known that L- WILLIAM M.

MITCHELL, a citizen of the United States,

residing at Louisville, in the county. of Jeffersonand State of Kentucky, have invented certain new and useful Improvements inRail-Anchors, of which I do declare the following to be a full clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The present invention hasfor its object to provide a simple and efiicient constructracks.

tion of rail anchor designed to prevent the longitudinal creeping of the rails of railway .The term rail anchor as used in this specification is intended to include not only the devices whichhave for their sole function the preventing of the longitudinal creeping of the rail but to include also tie plates or like devices to which my present invention is applicable.

The main object of the present invention is to provide an improved construction of rail anchor that can be readily applied to of this specification.

railway rails of diiferent sizes, and the .in-

vention consists in the novel features of im provement hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end the railway track being also shown- Fig.

In the various viewsjof theidrawings A designates a railway. rail ofj'ordinary con struction and providedwith the usual base flanges wand a", ties of the railway track]. '1 1 j In the form of the i "venti'on 'illustrated on Sheet. 1, my improved" rail anchor is shown as comprising 5 a-bddy niember C adapted to extend beneatlrjtlie'base flanges and B denotes one ofthe a of the rail A. One nd er the member 0 is provided with a jaw Dto'engage the rail flange a and preferably this jaw -D' is formed integral with' theinember'cl The opposite end of the niemberC 'is' provided with a jaw E formed sep'ara'te fromlthe member C of the railancl'ierand attached thereto in. such manner that as thejaw E .is forced into position} to engage the, flange a of the rail A, the jaw w ill 'movetoward' the rail flange a so that regardless ofthe exact size of the railfianges wand'at, the secure engagement of thei jaws .1) .and E with the flanges will'b'e eifected, whenitl1e jaw E is in position for use. Preferably,

the movable jaw E isui-provided upon its under side with a groove'adapted'to receive an upstanding zrib "Frat the end of the member C. As shown, this rib'F is formed integral with. theimember C. and

'upon'the upper face thereof. By reference more particularly to Figs. 2 and 3, it will be seen that the rib F is a dovetail rib, that is to say, it has outwardly extendng side portions f with which engage'the inwardly extending portions e of the jaw E. In order to insure that the jaw E, when it is'forced to position for use, shall move toward the flange a of the rail, the rib'F .is inclined toward the rail A and as shown,

backward movement of this jaw E. In the form of my invention illustrated on Sheet 1 of the drawings, the rib F is shown as provided with a plurality of teeth f adapted to be engaged by a pawl G that is suitably'connected, as by rivets g, to the jaw E. 'The free end 9' of the pawl projects slightly beyond the end of the jaw E so that when it is desired to withdraw the jaw E from engagement with the rail flange, it is only necessary to lift up the. .free -end of the pawl g todisengage it from the teeth f In applying to the railway rail A the improved construction of rail anchor shown on Sheet 1 of the drawings, the body member C'will first be slipped beneath the rail and the jaw -D will be engaged with one- 4 of the flanges a of the rail. The movable jaw E will then be engaged with the rib F- and the .jaw E will be moved in the direction of v the arrow, Fig. 1 until the inner gripping surface of the jaw E engages the'base a of the rail. As the aw E is thus moved along the rib F, the pawl G will ride overthe teeth f of the rib F and pawl G by its engagement with the teeth f will securely guard against any backward movement of the jaw E. Inasmuch as the jaw E moves toward the rail A as the jaw is being forced to its position for use, it will be seen that my improved anchor is adapted to be used with dlflerent s1z es of railway rails and this in practice will be found a very great advantage.

My invention is shown in the accompanying drawing as applied to that type of rail anchor in' which the body member C is provided with an abutment or foot C adapted to bear against one side of the railway tie C, though it will be readily understood that my invention is susceptible of wider application.

When my improved rail anchor 1s in position for use as indicated in Figs. 1 and In the form of my invention illustrated on Sheet 2 of the drawings, the body member' C of the rail anchor is shown as having a movable jaw E at the end farthest removed from the foot or abutment 'C of the anchor. In this form of my invention, such end of the anchor is provided with a raised rlb F corresponding to the raised rib F jaw E against the flange a of in the construction illustrated in Fig. l of the drawings and this rib F is engaged by the movable jaw E in the same manner as in the construction hereinbefore described. So, also the movable'jaw is shown as provided with a spring dog to engage'teeth formed upon the rib F, as in the construction above set forth. In this form of my invention, the opposite end of the body C is provided with a rigid jaw D to engage the base flange a of the rail A. The jaws E, E and D, D hereinbeit'ore described, may be formed as shown with projecting ribs,

in order to give the desired strength thereto and similar strengthening ribs may also be formed along the body member C and its abutment or foot that engages the tie B.

In the form of my'invention illustrated on Sheet 1 and-in the form illustrated in Figs. 5 and 6 oflthe drawings, the movable jaw is shown as engaging both the top and the edge of the rail base flange a, while the fixed jaw of the anchor is shown as engaging the top of the rail base flange only. It is obvious that both the fixed and the movable jaws may engage both the top and edges of the rail base flanges or may engage either the top edges of the flanges. Thus, in Fig. 7 of the drawings, I have shown a construction similar 'to that illustrated in Figs. 5 and 6, but in this form, both the fixed and rigid. jaws'are provided with'spaces or recesses 00 to prevent the jaws contacting with the edges of the base flanges a and a of the rail.

Instead of providing my improved rail anchor with only one movable jaw, both.

' jaws of the anchor may be movable, as illusadjacent the abutment C with a rib F simi lar in construction to the ribs F and F hereinbefore described, and upon thls rib F s mounted one of the movable jaws E that is provided with a slot to engage the rib F as in the constructions hereinbefore set forth,

a spring actuated pawl or detent G being placed upon the respective ribs F and F and will be moved in the direction of the arrow, Fig. 8, until the gripping portions of these jaws firmly engage the flanges a and a of the rail A. \Vhen the jaws have thus engaged the rail, they will prevent any tendency of the rail to creep in the direction of the arrow, Fig. 8, under the stress of passing trains. hen it is desired to release the rail anchor from engagement with the rail, it is Qnlynegessary to lift the pawls G until the pawls are disengaged from the teeth of the ribs F and F In the form of the invention illustrated on Sheets 4 and 5 of the drawings, the rail anchor is in the form of a rail tie plate. That is to say, the body member C rests upon the top of a cross tie B of the track and is connected therewith by spikes Z), these spikes passing through suitable spike holes formed in the body member. In this form of the invention, I have shown the body member as comprising a fixed jaw and a movable jaw, although it is obvious that two movable jaws might be used in this construction, as in that illustrated on Sheet 3 of the drawings. The tie plate is shown as of rectangular form and as having the fixed jaw D cast integral therewith, this jaw being of suitable construction to engage one of the flanges a of the railway rail A.

. Preferably, the body member C is provided with an abutment C adapted to bear against one side of the railway tie B At the opposite side of the body member C is; formed a raised rib F similar to the raised ribs hereinbefore described and similarly inclined inwardly toward the flange (4' of the railway rail A, the movable jaw E being formed with a groove properly shaped to engage the rib F As has been before stated, the movable jaws may be retalned in position for use and against accidental displacement in various ways, and 1n Figs. 11 and 12 of the drawings, 1' have shown the i aw E as having formed integral therewith a lug A which, after the jaw E has been forced into engagement with the flange a of the railway rail A, will be bent clownwardly, as shown in Fig. 11, so as to engage with the notches 0 formed at the edge of the body member C From the foregoing description it will be seen that any tendency of the rail A to creep in the direction of the arrow, Fig. 11, will be resisted by the engagement of the jaws D and E and any tendency of the body member C to move with the rail will be resisted by the abutment C as well as by the spikes b. If it is deslred to remove the movable jaw the bendable lug a may be bent upward until it 1s disengaged from the notches 0 after which the removable jaw E may be loosened by tapping the same with a hammer.

In the modification shown in Figs. 13 and 14 of the drawings, the construction is the same as that illustrated in Figs. 11 and 12, except that a somewhat different provision is made for holding the movable jaw E against accidental displacement. In this form of the invention, the movable jaw E is formed with one or more holes therethrough to receive the retaining pins H which pass through corresponding holes formed adjacent the edge of the body memher.

In Figs. 15, 16 and 17 of the drawings,

.there is illustrated another way in which the movable jaw E may be retained against accidental movement. In this modification of the invention, the body portion C will be similarto the body portion C shown in Figs. 11 andlQ, except that one edge of the body portion C will be formed with a series of notches 0 and the movable jaw IE will be correspondingly formed upon its under side and adjacent its outer edge with similar notches 6 when the movable jaw E has been brought to position for use and in engagement with the flange a of the rail, a pin K will be driven into two of the coinciding notches (as for example the central notches shown in Fig. 16) and this pin will prevent the accidental withdrawal of the movable aw E Preferably, the inner ends of the notches 0 will be depressed, as shown at e in Fig. 17, so that the inner end of the pin K, when it has been completely driven in, will be clenched downward and hence prevented froiiTaccidental withdrawal.

The operation and advantages of the various forms of my invention will be readily understood by those familiar with this class of devices.

In the form of the invention shown in Fig. 18, the body portion or member C is shown as provided at its opposite ends with abntments a similar to the abutment C in the construction shown iiiFigs. 8, 9 and 10 of the-drawings. In this form of the invention, the itongues or ribs F are similar to those sliinivn on Sheet 3 of the drawings, except that those tongues or ribs are inclined in the same direction. The movable jaws E are grooved similarly to the movable jaws shown onSheet3to engage the tongues or ribs F and spring pawls G are used to interlock the movable jaws with the teeth on the ribs F as hereinbefore described. This form of anchor is especially desirable for use on railways where traflic occurs in lVith this construction,

both directions over the same rails; and it is obvious that as the rails creep in one direction, the abutment at the right-hand side of Fig. -18 will be forced against a tie and the creeping of the rail in such direction will tend to more tightly wedge the adjacent jaw E against the base flange of the rail. On the other hand, if the rail tends to creep in the opposite direction, the abutment 0 at the left-hand side of Fig. 18 will abut against a tie and the adjacent jaw IE will be more tightly wedged against the base flange of the rail. liere two movable jaws are employed, it is obvious that the anchors are better adapted for the wider variance in the sizes of rails.

In the construction shown in Fig. 19, the

sist any tendency of the plate or anchor tomove in either direction with respect to the tie. In this form of the invention, the ribs or tongues F are shown as formed separate from the body member C and as connected thereto by rii'ets'f". The construction of the movable jaws E (one of which is shown by dotted lines in Fig. 19) is the same as that of the movable jaws hereinbefore described, these jaws being grooved to re-' ceive the .ribs F formed separate from and attached to the body member of the plate or anchor as in Fig. 19, my invention can be readily used in connection with various forms of tie, plates of familiar construction, it being only necessary to drill holes in the tie plates to receivethe rivets f whereby the ribs F are held in position upon the upper surface of the plate. hen the ribs F are thus formed separately, it will be a small matter to remove ordinary tie plates and apply my invention thereto.
